v Continue isolation of the problem under the direction of your next level of
support.
v Your next level of support may direct you to continue with this Problem
Isolation Procedure by going to step 1 on page 298 of this procedure.
This ends the procedure.
42. The failing item is one of three HSL I/O Bridges in the FC 5077 SPD Migrated
tower.
Use the associated packaging resources for the failing port identified in the
first failing resource row of “Appendix G. HSL Link Status Diagnosis Form”
on page 967. Determine the card type and card position of the HSL I/O
Bridge with the failing port(s).
43. Is the card type 2696?
Yes No
↓ Exchange the HSL I/O Bridge card using one of these symbolic FRUs
in the Migrated Expansion Tower Problem Analysis, Repair and Parts.
v Use LBSADP2 for card position S07.
v Use LBSADP3 for card position S10.
Then continue with step 45 of this procedure.
44. Exchange the HSL I/O Bridge card using symbolic FRU ″LBSADP1″ in the
Migrated Expansion Tower Problem Analysis, Repair and Parts.
45. Go to step 39 on page 293 of this procedure.
46. Is the second failing resource an I/O expansion tower?
Yes No
↓ Go to step 74 on page 297 of this procedure.
47. Locate and move to the frame identified in column ’A’ for the second failing
resource. Label the cables inorder to restore them later.
48. Disconnect the HSL cables.
49. Are the connections optical links?
No Yes
↓ Clean the HSL cable connector and port using the tools and
procedures listed in symbolic FRU “OPT_CLN” on page 561. Go to
step 51 of this procedure.
50. Wait at least 30 seconds.
51. Connect each of the cables to the other port (the one to which the other cable
was originally attached). The following will now be true:
v The cable originally connected to port 0 will now be connected to port 1.
v The cable originally connected to port 1 will now be connected to port 0.
Attention: You must fully connect the cable and tighten the connector’s
screws within 30 seconds of when the cable makes contact with the port. If
you do not the link will fail and you must disconnect and reconnect again. If
the connector screws are not tightened errors will occur on the link and it will
fail.
52. Refresh the port status by:
a. Wait 1 minute.
b. Select the Cancel function.
